Research on the influence of biostimulants and rooting substrate on the production of Lavandula angustifolia Mill. seedlings the 'HIDCOTE' variety
Abstract
Lavandula angustifolia Mill., belongs to the Lamiaceae family, genus Lavandula. This genus includes about 30 species with many subspecies, varieties, local populations and hundreds of hybrids selected for cultivation. The species are widespread in the Mediterranean area, Southern Europe, North-East Africa, Middle Eastern countries, South-West Asia, South-East India. It is a subshrub, with gray-green leaves and purple flowers, fragrant, aromatic, also considered a medicinal plant. It reaches a height of 30 to 70 cm, very well adapted to drier weather and higher altitudes (over 1800 m), but has been cultivated in various regions with temperate climates around the world. The biological material was represented by heel and ring cuttings of the species Lavandula angustifolia Mill. variety 'Hidcote'. The cuttings were harvested and made on 15.03.2023 from healthy and vigorous mother plants from their own lavender crop in Manaștur, Arad County. From the analysis of experimental data, it was observed that the substrate variants with the best results in terms of rooting are Peat TS4 Plus medium with perlite and clay, TS4 raw with Greenfibre, and the worst yield is given by Baltic Peat. The most effective biostimulator is the Quik-Link solution, followed by Razormin.
